Cylindrical toolbox

ABSTRACT

A cylindrical toolbox comprising a first housing, a second housing, a base, two lugs and a handle, wherein the first and second housings are combined to form a cylindrical body capable of accommodating parts and objects, while concavities for containing tools are disposed on both surfaces of the first and second housings.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a cylindrical toolbox, more particularly, a cylindrical toolbox formed by combining two housings, characterized in that concavities for containing tools are formed on the surfaces of the two housings, such that tools may be conveniently placed and obtained, and the cylindrical space formed by the two housings may also be utilized for placing other tools, parts or miscellaneous objects. Thus, by effectively utilizing the space formed by the toolbox, the present invention is capable of achieving the object of saving space and enhancing the degree of convenience.

[0003] 2. Description of Related Arts

[0004] Please refer to FIG. 10 and FIG. 11, which are the pictorial views of the conventional toolbox 80. The conventional toolbox 80 comprises an upper cover 81, lower cover 82, a hinge 83, fastening portions 84 and a handle 85, wherein the inner surfaces of both the upper cover 81 and the lower cover 82 are disposed with a plurality of concavities 86 for accommodating all kinds of tools. The hinge 83 is utilized for pivotally fastening both the upper cover 81 and the lower cover 82 at the rear ends thereof, and the fastening portions 84 are disposed at two ends on the front edge of the upper cover 81. Two grooves 87, corresponding to the fastening portions 84, are respectively disposed at two ends on the front edge of the lower cover 82 for engaging with the fastening portions 84 so as to allow the upper cover 81 and the lower cover 82 to shut and close.

[0005] As the toolbox 80 is shut, as shown in FIG. 10, the fastening portions 84 on the upper cover 81 are to engage with the grooves 87 on the lower cover 82, thus a portable toolbox 80 is formed. If the user is to obtain tools contained in the toolbox 80, the fastening state between the fastening portions 84 and the grooves 87 should be released first, and then the upper cover 81 should be lifted so as to take hold of various tools such as hammers, pincers, nippers, flat-head screwdrivers or phillips screwdrivers.

[0006] The user, when using the conventional toolbox, has to lift the cover to take hold of tools contained therein, a procedure that causes inconvenience; moreover, concavities in the conventional toolbox are designed for specific tools, causing the conventional toolbox not being able to contain extra tools brought in, such that extra expenses have to be incurred to the user for a new toolbox.

SUMMARY OF THE INVENTION

[0007] The object of the present invention is to provide a cylindrical toolbox with containing spaces being formed on the surface thereof for containing tools therein, and an internal space being formed inside the cylindrical toolbox for containing other tools, parts and miscellaneous items, so as to effectively utilize spaces.

[0008] The cylindrical toolbox achieving the foregoing object comprises a first housing with one side thereof disposed with at least one first fastening device, a second housing with one side thereof disposed with at least one second fastening device, and a base engaging with the bottoms of both the first and second housings. A plurality of concavities for containing tools are disposed on both surfaces of the first and second housings, and the first housing and the second housing are fastened by the first fastening device and the second fastening device so as to form a cylindrical cavity.

[0009] Two lugs can further be mounted respectively on the top portions of the first and second housings.

[0010] The first housing and the second housing are both hollow bodies with the outer shape thereof capable of being any shape such as cylindrical or cuboid.

[0011] The base can be rotatable.

[0012] Two ends of the handle are to extend outwardly to respectively form two straight rods that connect to the inner sidewalls of both the first and second housings.

[0013] Two ends of the handle are to extend inwardly to respectively form two straight rods that connect to the outer sidewalls of both the first and second housings.
